My Harman TL-300 has the best secondaries. Possibly because the flue gas exits out the bottom of the firebox in the back. I get a curtain of free floating flame that makes its way out to the upper door glass, then it catches the air wash going down and slowly falls to the bottom of the stove and disappears into the base of the wood pile on its way to the rear bottom exit. Ill take a video of that next time.
